Multiply the values across the rows. So you'll multiply each mark with its corresponding frequency

6*5 = 30

7*4 = 28

8*7 = 56

9*10 = 90

10*4 = 40

Then add up those results

30+28+56+90+40 = 244

Finally, you divide by 30 since this is the total number of scores (add up everything in the second column of the original table to get 30)

So we end up with the mean being 244/30 = 8.133 approximately

Round that value however you need to.

What is the volume of a cylinder that has the same base and height dimensions as the cone shown below? Use 3.14 for pi the base
Zarrin [17]
Answer: I assume the radius is 1/2 the base of 6 in.

r = 3 ft
h = 10 ft
s = 10.4403 ft
V = 94.2478 ft³
L = 98.3976 ft²
B = 28.2743 ft²
A = 126.672 ft²


r = radius
h = height
s = slant height
V = volume
L = lateral surface area
<span>B = base surface area </span>
A = total surface area
π<span> = pi = 3.14159</span>
<span>√ = square root</span>
